 ---------
 
 PHP malware scanner is [licensed](https://github.com/scr34m/php-malware-scanner/blob/master/LICENSE.txt) under the GNU General Public License v3.
+
+Docker Usage
+-----------
+
+You can also run the scanner using Docker:
+
+1. Build the image:
+```bash
+docker build -t php-malware-scanner .
+```
+
+2. Scan a directory:
+```bash
+docker run -v /path/to/scan:/code php-malware-scanner -d /code
+```
+
+For example, to scan a WordPress installation:
+```bash
+docker run -v /var/www/html:/code php-malware-scanner -d /code -j 6.4.1
+```
+
+Common usage with flags:
+```bash
+# Show only infected files (hide OK status)
+docker run -v /path/to/scan:/code php-malware-scanner -d /code -k
+
+# Show comments for matched patterns
+docker run -v /path/to/scan:/code php-malware-scanner -d /code -c
+
+# Show MD5 hashes and continue after first match
+docker run -v /path/to/scan:/code php-malware-scanner -d /code -m -s
+```
+
+The `/code` directory inside the container is where your files will be mounted for scanning.
